摘 要:通过在丁苯橡胶后处理单元添加促进剂的方式改善环保型丁苯橡胶SBR1739的硫化速度,研究促进剂的种类、加入方式及用量对橡胶硫化速度和物理机械性能的影响。结果表明,选择N-乙基-N-苯基二硫代氨基甲酸锌(简称PX)、2、2′-二硫代二苯荓噻唑(简称DM)、三烷基氯化铵(简称P-60)和[1,6-(双N,N′-二苯荓噻唑氨基甲酰二硫)-己烷](简称WY988)为促进剂时,P-60和WY988可有效改善橡胶的硫化速度和物理机械性能。胶样采用干法填充促进剂时,胶样的硫化速度和物理机械性能均优于湿法填充,干法填充P-60用量为0.05份时,橡胶的硫化速度提升22.5%,拉伸强度提升28.7%。The paper improved the vulcanization rate of environmentally friendly styrene butadiene rubber SBR1739 by adding accelerators in the post-treatment unit of styrene butadiene rubber,and investigated the effects of accelerator type,addition method,and dosage on rubber vulcanization rate and physical and mechanical properties.The results showed that N-ethyl-N-phenyldithiocarbamate zinc(PX),2,2′-dithiodibenzothiazole(DM),trialkylammonium chloride(P-60),and 1,6-(bis N,N-dibenzothiazole aminoformyl disulfide(WY988))as promoters,P-60 and WY988 could effectively improve the vulcanization rate and physical and mechanical properties of rubber.When the dry filling accelerator was used for the rubber sample,the vulcanization speed and physical and mechanical properties of the rubber sample were better than those of the wet filling.When the amount of trialkylammonium chloride used in the dry filling was 0.05 parts,the vulcanization speed of the rubber is increased by 22.5%and the tensile strength was increased by 28.7%.
